Embodiment 1
[0025] The raw materials used for the polystyrene crosslinked divinylbenzene resin honeycomb body in this example are: based on the total mass fraction of 100%, including polystyrene crosslinked divinylbenzene resin powder 84%, water-based acrylic acid emulsion 5%, fat Amide 1%, Phosphate 1%, Carboxymethyl Cellulose 2%, and Attapulgite 7%.
[0026] The specific preparation steps of the polystyrene crosslinked divinylbenzene resin honeycomb body are:
[0027] Step (1): Add 6 L of polystyrene cross-linked divinylbenzene resin particles and 6 L of deionized water into the grinding barrel of the ball mill, and the ratio of ball to water is 2:1:1. Add all the materials successively in the order of 2L polystyrene cross-linked divinylbenzene resin particles + 2L deionized water + 4L ball mill. After sealing, grind at a speed of 30 rpm for 8 hours to obtain a slurry-like resin. Slurry resin can pass through a 300-mesh sieve;
[0028] Step (2): The slurry resin is subjected to vacuu...
Embodiment 2
[0032] The raw materials used for the polystyrene crosslinked divinylbenzene resin honeycomb body in this embodiment are: based on the total mass fraction of 100%, including polystyrene crosslinked divinylbenzene resin powder 49%, epoxy resin 20%, fat Amide 3%, Phosphate 3%, Polyacrylamide 5%, and Bentonite 20%.
[0033] The specific preparation steps of the polystyrene crosslinked divinylbenzene resin honeycomb body are:
[0034] Step (1): Add 6 L of polystyrene cross-linked divinylbenzene resin particles and 6 L of deionized water into the grinding barrel of the ball mill, and the ratio of ball to water is 2:1:1. Add all the materials in the order of 2L resin + 2L deionized water + 4L ball mill. After sealing, grind at a speed of 30 rpm for 8 hours to obtain a slurry-like resin. Slurry resin can pass through a 300-mesh sieve;
[0035]Step (2): The slurry resin is subjected to vacuum filtration (double-layer filter paper with a pore size of 0.22 μm, pressure −0.07 MPa) to ...
Embodiment 3
[0038] The raw materials used for the polystyrene crosslinked divinylbenzene resin honeycomb body in this embodiment are: based on the total mass fraction of 100%, including polystyrene crosslinked divinylbenzene resin powder 87%, phenolic resin 5%, twelve Sodium Alkylbenzene Sulfonate 1%, Phosphate 1%, Carboxymethyl Cellulose 1%, and Kaolin 5%.
[0039] The specific preparation steps of the polystyrene crosslinked divinylbenzene resin honeycomb body are:
[0040] Step (1): Add 6 L of polystyrene cross-linked divinylbenzene resin particles and 6 L of deionized water into the grinding barrel of the ball mill, and the ratio of ball to water is 2:1:1. Add all the materials in the order of 2L resin + 2L deionized water + 4L ball mill. After sealing, grind at a speed of 30 rpm for 8 hours to obtain a slurry-like resin. Slurry resin can pass through a 300-mesh sieve;
[0041] Step (2): The slurry resin is subjected to vacuum filtration (double-layer filter paper with a pore size ...
